UFCThe Ultimate Fighting Championship (UFC) is a U.S.-based mixed martial arts organization, recognized as the largest MMA promotion in the world. The UFC is headquartered in Las Vegas, Nevada and is owned and operated by Zuffa, LLC. This promotion is responsible for solidifying the sport's postion in the history-books.
UFC is currently undergoing a remarkable surge in popularity, along with greater mainstream media coverage. UFC programming can now be seen on FOX, FX, and FUEL TV in the United States, as well as in 35 other countries worldwide.

As MMAjunkie.com previously reported, UFC interim champ Renan Barao is injured and out of next month's UFC 161 event. With little time to find a suitable replacement, the night's co-feature between Rashad Evans (17-3-1 MMA, 12-3-1 UFC) and Dan Henderson (29-9 MMA, 6-3 UFC) has been promoted to headlining status.

UFC officials today made the change.

UFC 161 takes place June 15 at MTS Centre in the Canadian city of Winnipeg. The main card airs on pay-per-view following prelims on FX and Facebook.

Evans, who had won four straight fights after losing his title to Lyoto Machida in 2009, looks to end a two-fight losing streak after dropping back-to-back decisions to current light heavyweight champion Jon Jones and Antonio Rogerio Nogueira.

The 33-year-old had flirted with the idea of a potential move down to middleweight in recent months but instead will face Henderson, who dropped a close split decision to Lyoto Machida this past month at UFC 157. The loss, which snapped a four-fight win streak and came after a 15-month injury layoff, likely cost the 42-year-old a title shot.

Barao looked to defend his interim title for a second time as champion Dominick Cruz recovers from a knee injury. Barao, who's won 30 straight fights (and five straight in the UFC), defended his interim belt for the first in February with a submission win over Michael McDonald.

His original opponent, Eddie Wineland, a former WEC champion, recently fought his way back into title contention with back-to-back wins over veterans Scott Jorgensen and Brad Pickett. Wineland's next move has yet to be announced.

With the loss of the Barao vs. Wineland contest, the UFC 161 main card has room for one more fight. It's currently unknown if UFC officials will secure a new opponent for Wineland or promote another contest from the evening's preliminary card

I think we have gone from an exciting main event to this which i think will be a boring one.

Eugh, this fight is going to suck. Not really looking forward to this event much at all. Best fight on the card will be Barry vs Jordan, and that's only because Pat Barry is a massive legend. Rest of the card is terrible.

Henderson did not look good or even healthy against Machida. If that Dan shows up it won't matter what Rashad does he's going home with a decision.

I'm seeing this going a lot like Shad v Rampage. Lot of fence work for five rounds. However if Rashad gets in that zone where he thinks he's Floyd mayweather where he moves his head until he actually does something he'll be waking up as another meme.
